v :Appiiation ined April 22,

This invention vrelates to an attachment for sewing machines, and one ofthe objects thereof is to provide a-new and improved-devicefor attaching a strip of fabric, having hooks or eyes mounted thereon, to a garment or to Ianother piece of fabric.

Another object of the invention is to provide a device of the above character, which while joining the hook or eye carrying strip o of the garment or other piece of fabric, will bindthe free or raw edge of the material of said last element, adj acentits point of joinder with the hook or eye carrying strip'.

Another object of the invention isto providey a new Vand improved device yfor siinultaneously positioning and'stitching together,

and'binding 'one of the edges of 'a hook and eye carryingstrip and Yagarment or other piece of fabric.

' more or less specificthan thosev referred to above, will be in part obvious and inpart pointed out in the course of the following description of theelements, combinations, arrangements of parts and applications of principles, vconstituting theiinvention, and the scope of protection contemplated will bein-V d'icated in the appended claims.y

Referring now to the drawing, wherein similar reference characters vrefer to similarV parts throughoutthe views-thereof,:the refer'- `ence numeral 1 denotes la portionofthe table or platen of a sewing Smachine,having the usual apertures orslots y2, through which the fabric'feedingy devices are projected to en- 1924.'

gage and fvfeed the `.fabric.- The aperture through whichthel needleworks is indicated at 3.

vIf desired, the table limay bea separate *y attachment, and be secured to the table proper' f jof the sewing machine by means extending through the aperture il.

Pivotally and adjustably mounted upon thetable 1, is a'plate 5, the securing and adjusting means-comprising a screw 6, threaded into the table 1, which extends through a slot in the plate 5. vrl`his plate, when the device is in operation, is immovably securedto the table 1, if a proper adjustment has been effected- "f` Pivotally mounted' to the plate 5'by means of the screw7 is a bracket plate 8,-which is adapted to -lie closely adjacent the plate 5,

y so that it can bel swung into the position Other objects andl aims of the invention,

shownin full lines of Figr1, or to the position v `shown in thedotted lines in said figure. u The full-lines show the normal or workingposif tions ofthe parts, f "Threaded through an upstanding flange 9 screw 1 0, the edge of which is adapted to engagewith the edge 11 of plate 8, whereby the normal position of plate 8 may be adjustably determined. A leaf-spring 12 `fastened to the bracket plateSy by the screws 13,.is provided with a flange end 14, which engages the flange fo'ri'nedinthe plate, is a stop or abutment A v9 tohold said'bracket plate@ inits normaler working position.V

in the dotted lines of Fig. 1, the flanged end 14 of theleaf-spring 12 'will ride over the fiange'9 and permit the outward'swinging of the bracket plate, and thatwhen the latter is swung to itsnormal position, the flange 14 of said leaf-spring will again ride over the flange Qofthe plate 5, whereupon the parts. will thereafter be maintained in theirznormal 1 positions. u

`.Adjustably mounted upon the forward i edge of the bracket plate 8, yasby means of the rtherefore it is not necessary to illustrateit or specication. l`This device Operates upon a strip of binding fabric, suchiforinstance as is shown `atl?, andfolds it upon itself along' a median line, and then turns each of the Vfree 10o screws 15-,is a binding folder 16j lf lhisbi-nd- 1 i Ning folder is of a known construction-,land` edges of said strip inwardly and rearwardly upon itself, as indicated at 18 in Figure 3.

Carried upon the folding device 1.6 is a platform 19, which when the parts are in normal positions, over-lies the forward edge of the table 1, and is spaced vertically therefrom.

Mounted in a groove or recess 2() formed in the upper forward face of the table 1, is a guide 21., which guide is formed of a strip of metal7 the edges of which are bent upwardly and inwardly to provide the passageway 22. The free edges 23 and 24 of this guide member terminate short of each other to provide the slot 25.

The uide 21 adapted to receive a strip of fabric upon which has been mounted preferably by the rivets 26 a plurality of hooks or eyes 27, and the slot 25 is so disposed, and is of a sufficient width, to receive the'rivets 26, the edges and 24 of said slot serving to guide the fabric strip, indicated at 28, through the engagement of the rivets with said guide member.

Thus it will be seen that strips similar' to 28, of different widths, may be passrd through the guide 21, inasmuch as the guiding is done by the engagement of the riifets of the hooks or eyes with the edges 23 and 24 of the slot 25. The slot 20 of the table 1 is provided with an incline 29, which rises rearwardlyto a level with the face of the table 1. i

Referring now to Figures 1 and 2 of the drawings, it will be seen that the inner end 30 of t e folder 16,: when the parts are in normal position, is disposed directly above the hooks or eyes carried upon the stri-p28, providing av U-shaped space inthe folded binding strip 17, `through which may be passed the edge 31 of the garment 32, or other piece of material, which is to be attached to the hook or eye carryingstrip. 1

The garment or other piece of fabric 32, passes over the platform 19, so that the edge thereof is received in the folded portion of the binding material, and the parts are so disposed relativ-e to the needle, that the needle, `when in operation, will pass through the inwardly turned edges of the binding niaterial, the edge of the garment or other piece of fabric 32, and ythe hook or eye carrying strip 28, whereby the edge 3l of the garment 32 will be bound while being stitched to the hook or `eye carrying strip28.

In practice the parts are so related that the line of stitching, indicated at 33, will pass through the layers of fabric directly behind i the point of fastening ofthe hooks or eyes 27 `to the strip 28, so that the bound edge 31 of hoo ts or eyes. i

'Mounted upon the table or plate 1 is a guide member 34,the latter comprising a screw, the shank 35 ofwhich is threaded into an aperture formed inthe table. This screw is provided with a pair of circular shoulders 36 eyes.

will partly overlie the fabrics, and is adapted to engage with theV edge of the hook or eye `carrying strip `28. Thus it will be seen that this strip 28 is guided to travel in a straight direction, bothV in front and behind stitching means comprising the needle, which is indicated at 38.

Having thus described the construction of this embodiment of my invention, the operation thereof which should be largely linderstood, is as follows: Y

The parts being positioned as shown in Figs. 1 and 2, the strip of binding is fed into the folder 16, as illustrated in said figures, and a hook or eye carryingstrip, such as shown at 28,is fed to the guide21. These strips are thereafter then automatically fed to their respectivefolding or guiding devices by the feed mechanism of the sewing machine. p 1 f p l The operator then passes the edge ofthe garmentror strip of fabric l32 over the platform 19, so that the `edge thereof passes through the fold, indicated at 39,01 the binding, whereupon the parts are fastenedto. gather by the operation of the needle to form the line of stitching 33.

As has already been explained, the hook or eye carrying strip 28-is positively` guided at both sides of thestitching means, and the in* ner end 30 of the binder 16 is disposed to, discharge the folded binding material directly above the fastening devices of the hooks or Therefore, it will be seen that once the strips of fabric are caught by the stitching means, it is `merely necessary for the operator to maintainthe edge of the garment, or other piece of fabric, in engagement withV the fold 30 to insure that the parts will be in their proper superimposed relation when they reach the stitching means.

It will accordingly be seen that I have provided a construction well adapted to attain, among others, all the aims `and objects above pointed out, in a simple and facile manner, and I have provided a device which will perform its functions with exactness and pre,- cision, while at the same time effectingla considerable saving of labor. 1

As many changes could be made in this construction without departing from the scope of the `folliiwing claims, it isintended that all matter contained in the above description or shown `in the` accompanying only and not in a limiting sense.
